Xanthine Derivatives Quantification in Serum by Capillary Zone Electrophoresis

Analysis of micafungin in serum by capillary zone electrophoresis.

A method is developed for measuring the concentration of micafungin, an echinocandin antifungal agent, in serum, using capillary zone electrophoresis. With a 0.1M borate buffer (pH 10.0) as the run buffer, detection is carried out at 200 nm. Pretreatment is performed by adding acetonitrile to serum (1:2) for deproteinization, allowing the supernatant fluid to be taken for measurement. The detec...

Serum succinate by capillary zone electrophoresis: marker candidate for hypoxia.

Serum succinate may offer an alternate analyte to lactate for the evaluation of hypoxia. To evaluate the potential uses of succinate, a relatively rapid capillary zone electrophoresis assay was developed for use in the clinical laboratory setting. Employing a simple indirect ultraviolet detection method with commercially available instrumentation, the limit of detection for serum succinate was ...

Quantification of Carbohydrates in Grape Tissues Using Capillary Zone Electrophoresis

Soluble sugars play an important role in freezing tolerance in both herbaceous and woody plants, functioning in both the reduction of freezing-induced dehydration and the cryoprotection of cellular constituents. The quantification of soluble sugars in plant tissues is, therefore, essential in understanding freezing tolerance. While a number of analytical techniques and methods have been used to...

Evaluation of Acetonitrile Deproteinisation of the Serum Samples for the Analysis of Drugs in Serum Using Capillary Zone Electrophoresis

Deproteinisation with acetonitrile (along with methanol or other reagents) is a useful and rapid technique in analysis of drugs or their metabolites in human serum. In this paper application of this simple technique in biopharmaceutical analysis using capillary electrophoresis (CE) is evaluated. Some drugs with different ionic and protein binding properties were selected and dissolved in human ...
